A neighbour of the local Hackspace has got (second) CNC machine. In order to avoid complaints about the noise from people on the other side of concrete floors, he has built a heavy enclosure to deaden the sound. It has the secondary advantage of protecting his ears.
Before building an enclosure, it might be worth assessing whether your machine will be too noisy, for any relevant definition of "too".
Yeah, especially if you plan on using a vacuum bed; that one extra blower seems to double the noise factor on every CNC router table I've ever run. Makes it ALMOST worth the assache of clamping the work down.

Never heard of a "ton" (2000 pounds = 1 ton) referred to as a "short ton". Other than a metric ton (1000 kg) never distinguished it from any other unit of weight.
Oh you crazy Americans and your 'freedom units'
I used to work with Farmers way back when some still talked in chains, rods and inch acres of water
Viva La Metric System I reckon.
Oh boo! I'll stick with my inches, feet, yards, miles, pounds, Fahrenheit, etc thank you very much!
That is something I don't relish about moving to Canada... trying to remember the difference in degrees. Aside from that though... not much of a problem; most of the stuff I actually work with is metric system anyways, due to coming from Asia.
Why is it that Asian-made sockets and wrenches in SAE sizes, which sell only to one benighted nation, ALWAYS come in complete sets... while the metric sets which the WHOLE WORLD (fuck you, Whitworth) USES, even the "good ones", always have several missing?

It's not like you don't NEED those missing sizes; there's ALWAYS one of them you have to fight with,

and it's getting now so you can't even buy the missing ones as singles, either...

100 kliks ≠ 60 miles, just as 12" ≠ 13mm and 5/8" ≠ 16mm.
